An Alabama teen is being criticized after posting a selfie at the Auschwitz concentration camp.

Breanna Mitchell, an 18-year-old from Roanoke, Ala., said just before her senior year, she and her father planned a trip to Poland. However, unexpectedly Mitchell's father died of a heart attack right before she started her last year at Handley High School.

Mitchell continued to go on the trip with her grandmother in memory of her dad, and visited Poland last month.

"I expected it to be really sad because I knew he wasn't there, but when I got there I could feel him with me," Mitchell told AL.com Thursday.

She said she had been taking pictures throughout the camp. "Me, being a teenager, decided to take a selfie."

That selfie at the Auschwitz concentration camp resulted in a social media uproar.

"I guess it was an in the moment thing. But people have just taken it so far," Mitchell said.

"They have photobombed my picture with the World Trade Center. I don't understand why."

Mitchell said a week after she tweeted the selfie, a girl tweeted her asking how she could post something like that. Two weeks later, Mitchell said she was bombarded with notifications on her social media accounts.

"There were death threats. Somebody told me he would come over and poison me," Mitchell said. But she also said some people "were considerate of me and have been taking up for me."

When asked if she has contacted law enforcement about the threats, Mitchell said the comments don't bother her.

"Half the time I don't even read them. There's some I do read, but I say whatever these people will never see me in their lives," Mitchell said.

She said she has always been interested in the Holocaust and it was a topic she often discussed with her dad.

"I'm not a history person but that's the only part of history I'll actually sit there and talk about. I guess it's so weird all that could happen and nobody could do anything about it," Mitchell explained.

She said in the ninth grade a teacher set up a web cam interview with a Holocaust survivor living in Atlanta and that experience had a big impact on her.

In the spring Mitchell will start school at the Southern Union State Community College in Opelika. She said she's debating on becoming a nurse or a ninth grade history teacher.
